Light implementation of Event Sourcing using PostgreSQL as event store2023 · github.com · ▲231Hi everyone, If you have a Java Spring Boot application with a PostgreSQL database, you can implement Event Sourcing without introducing new specialized databases or frameworks. If you have an application dealing with an entity called Order, you should adopt Event Sourcing to keep track of all changes, and know how the Order got into the current state. Event Sourcing gives you: 1. the true history of the system (audit and traceability), 2. the ability to put the system in any prior state (debugging), 3. the ability to create read projections from events as needed to respond to new demands.…

Bringing multithreading to Python's async event loop2024 · github.com · ▲82This project explores the integration of multithreading into the asyncio event loop in Python. While this was initially built with enhancing CPU utilization for FastAPI servers in mind, the approach can be used with more general async programs too. If you’re interested in diving deeper into the details, I’ve written a blog post about it here: https://www.neilbotelho.com/blog/multithreaded-async.html
- WMWebReducer – micro event sourcing cloud function2022 · webreducer.dev · ▲10
Hey everyone, WebReducer is a project I've been working on since last December. You can read about my process here: https://offbyone.us/tags/micro-business/ Send some data to WebReducer. Then, write a reducer function to retain some state. You can change the reducer function as much as you want and recreate that state. Still working on how to explain it. It's a tiny FaaS platform. It's a tiny database. It's micro event sourcing. It's "redux" on the server as a service. It's a backend for tiny personal projects. It's a place to send your webhooks. I'm looking for…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
